Scientists have developed the first ultra-thin, flexible
device that sticks to skin like a rub-on tattoo and can detect a person’s
glucose levels. The sensor, reported in a proof-of-concept study in the ACS
journal Analytical Chemistry, has the potential to eliminate finger-pricking
for many people with diabetes.
Joseph Wang and colleagues in San Diego note that diabetes
affects hundreds of millions of people worldwide. Many of these patients are
instructed to monitor closely their blood glucose levels to manage the disease.
